Santos exited Saturday's 131-122 loss to the Suns with an undisclosed injury and did not return, Anthony Slater of ESPN.com reports.
Santos limped to the locker room during the third quarter, ending his evening with seven points (1-4 FG, 1-2 3Pt, 4-8 FT), four rebounds, three assists and one turnover across 23 minutes. For now, Santos should be considered questionable for Monday's game in Denver.
